A high-insulation pallet container is an especially good option for storing fresh fish or other products on ice or liquid ice in order to maintain its initial quality and thus maximize its value. We recommend using ice made from fresh water, because sea water ice can make the contents freeze. The appropriate amount of ice depends on conditions such as temperature and intended storage time. The general rule is that approximately 30 to 40 % of the content should be ice. This, however, depends on external conditions.The high-insulation type is lighter than the heavy- duty type and is therefore preferable where containers need to be moved manually.The polyurethane (PUR) foam insulation between the PE walls of the container is the key to the insulating properties of the high-insulation type. The average density of insulation is 43 g/l (kg/m3).
